Stable Liquid Cleansing Compositions Comprising Critical Window of Partially Hydrogenated Triglyceride Oil of Defined Iodine Value

Abstract

The present invention provides personal wash compositions where partially hydrogenated triglyceride oil (defined by IV of 20 to 100) are specifically formulated to provide low temperature stability. Specifically when formulated to have specific concentration of partially hydrogenated triglycerides, delivered alone or as part of mixture with other oils, desirable low temperature stability of formulations is achieved.

Description

FIELD OF THE INVENTION[0001]The present invention relates to stable liquid personal wash compositions comprising both long chain fatty acids (used to provide skin functional benefits like to mildness and moisturization) and partially hydrogenated triglycerides of defined IV value and / or mixtures of partially hydrogenated triglycerides of defined IV values and other oils. The partially hydrogenated triglycerides (defined by iodine value IV value of 40 to 100, preferably 50 to 90) stabilize the compositions over a wide range of storage temperatures. More specifically, the partially hydrogenated triglyceride and mixtures of such with other oil prevent low temperature composition instability caused by high melting point components (long chain fatty acids, for example) found in the liquid cleansing formulations. Use of critical amounts (e.g., minimum amount within defined IV window to provide sufficient crystallinity to stabilize liquids) of partially hydrogenated triglyceride in liquid ...

Problems solved by technology

However, the oil phase in liquid cleansing formulations can challenge formulation stability because of the incompatibility between the aqueous continuous phase and the water immiscible oil phase.

A problem in the art is how to provide long term stability over a wide range of transportation/storage temp
